DROP-CYLINDER FOR VAPOR-LAMPS.

SPECIFICATION forming part of Letters Patent No. 665,129, dated January1, 1901.

Application filed September 14, 1899. Serial No. 730,434. (No model.)

To all whom it may concern:

Be it known that I, WIRT STANLEY QUIG LEY, a citizen of the UnitedStates of Amen ica, and a resident of Philadelphia, county ofPhiladelphia,and State of Pennsylvania,have invented certain new anduseful Improvements in Drop-Cylinders for Vapor-Lamps, of which thefollowing is a specification.

My invention relates in general to vaporburning lamps; and morespecifically it consists of an improved apparatus for facilitating thepreheating of the vaporizing apparatus and the protection of theincandescent mantles frequently used upon this kind of lamp.

To this end the apparatus consists of a cylinder adapted to telescope upinto the chimney of the lamp when the same is in regular operation andto drop down so as to surround the incandescent mantles when the lamp isput out or when it is being started into operation.

The preferred form of apparatus embodying my invention is illustrated inthe accomfigures refer to. like parts.-

panying two sheets of drawings, in which- Figure 1 is a vertical sectionof the lamp on line 1 1 shown in Fig. 2, parts of the lamp on theleft-hand side being broken away instead of being shown in section. Fig.2 is a side elevation of the lamp shown in Fig. 1 with some of the upperparts broken away.

Throughout the drawings like reference- The lamp illustrated is one ofthe species of lamps known as cluster-lamps, having a plurality ofburners 1 1, each provided with an incandescent mantle 2 2 of the usualWelsbach type. These burners are supported from a suspended frameworkhaving a cylindrical metal chimney 3 and a hemispherical glass globe 4.A vaporizing-tube 5 extends through and across the chimney above theburners and mantles, said vaporizing-tube having a connection 5 with thesource of oil-supply. (Not shown.) The vaporizing-tube 5 usually has aV-shaped saddle 6 supported over it for the purpose of concentrating theheat upon it, and said saddle may be lined with asbestos or otherincombustible material, as shown at 6 This saddle 6 is supported fromthe lower end of the hanging rod 9, by which the entire lamp issuspended.

Within the chimney 3 is arranged a short metal cylinder 7, adapted totelescope into the chimney, as shown in full lines, or to drop downbelow it into the position shown in dotted lines. 1 (See Fig. 1.) Thistelescoping cylinder 7 has across-piece 8 extending diametrically acrossand preferably slightly above its upper end, said cross-piece beingprefer- This bent rod has its central portion 8 coiled and down on andbe guided by said suspension-rod. I

A crank-shaft 10 is journaled in the upper portion of the chimney 3 andextends across the same a little to one side of the center The centralbent or crank portion 11 of this crank-shaft cooperates with thecross'piece 8 of the telescoping cylinder by bearing on the in itsuppermost position, as shown in Fig. 2, it drops into the small recess16, formed-on the under side of said cross-piece by the curvatn re giventhereto. The crank-shaft lO-extends outside of the chimney and isprovided it a partial rotation. The telescoping cylinder 7 has verticalslots 13 13 formed therein, through which the vaporizing-tube 5 passesand which permit of the up-and-down motion of said cylinder abovereferred to.

A bridge-piece ,14 extends diametrically across the upper portion of thelam p-chimney and is fastened to the suspension-rod 9 in any convenientmanner, thereby affording means for supporting the lamp from saidsuspensionrod, as best shown in Fig. 2. An ordinary cap or deflector 15is mounted above the chimney, and a piece of wire-gauze 17 bridges overthe space between said deflector and the top of the chimney.

The mode of operation of my invention is as follows: When the lamp is inregular operation, the parts are as shown in full lines in the drawings.When the operator desires to put out the lamp in the ordinary manner byshutting off the supply of oil, he may first drop the telescopingcylinder? by turning the position shown in dotted lines in Fig. 1. Thisprotects the mantle 2 2and leaves the ably made in the form of the bentrod shownr about the suspension-rod 9, so as to slide up under sidethereof, and Whensaid crank is with a handle 12 or other means forgiving the handle 12, so that the parts will assume thereof, so as toclear the suspension-rod 9.

parts in the proper position for starting up the lamp. eration, thevaporizing-tube 5 of course has to be preheated by any one of a varietyof means commonly used in these lamps, such as a flame of alcohol-vaporor of a heating gas-burner, (none of such means being shown in thedrawings, however,) and the position of the telescoping cylinder 7, asshown in dotted lines, assists materially in extending the degree towhich the parts of the lamp surround and inclose the vaporizing-tube 5,so that the heating-flame is concentrated more closely upon thevaporizing-tube 5 and protected from side drafts and other causes whichmight tend to dissipate the heat. Although the preheating-flame from thegasburners or other source heats the vaporizing-tube to the necessarytemperature before oil is admitted, the other parts of the lamp stillremain comparatively cool, and the initial jet of vaporized oil is thusdischarged into a cold mixingtube, where it is mingled with a body ofcomparatively cold air and the partlychilled mixture passes up through acold burner under a cold mantle. The result of this is to render theinitial How of combustible mixture from the vapor-burner somewhat feebleand to produce a tendency to condensation in the lower end of themixing-tube. The cylinder 7 when in its lowered position serves topromote the initial operation of the lamp by throwing down upon theburners and mantle a portion of the heat of the preheating-flame.

"Vhen the oil is turned on and the vapor begins to issue from theburners 1 1, the cylinder 7 also assists in leading said stream of vapordirectly upward to the vaporizing-tube, where it is ignited by thepreheating device, and the heat generated by said burners is alsoconducted directly to the vaporizing-tube until the lamp reaches thestage of perfect operation. Thus the cylinder 7 serves to shorten thetransition period from the operation of the lamp by thepreheating-burner to its self-supporting operation from the vaporburner,reduces the tendency to condensation of oil during the startingoperation, and prevents the tendency of the lamp to smoke during thisperiod. The crank-shaft 10 is then given a partial rotation by thehandle 12, so as to telescope the cylinder 7 up into the chimney, whereit disappears from view, and the crank portion 11 drops into thedepression 16 and is retained in its elevated position until a positiveforce is again applied to the crank-shaft to drop it down again and alsothe cylinder.

The advantages of the invention are those previously described in theprotection of the mantles and the concentration of the heat upon thevaporizing-tube during the operation of starting up the lamp, and alsothe fact that the internal cylinder 7 when in its raised position actsas a lining for the chimney, protecting the other parts of the lamp fromthe great heat produced and also pre- Vfhen the lamp is started intoop-.

venting in part the radiation of said heat through the chimney. This ofcourse tends to increase the draft of the lamp and renders its operationmore perfect.

It is evident, of course, that various changes could be made in thedetails of construction illustrated without departing from the spiritand scope oi": the invention so long as the general relative arrangementof parts or the principle of operation is preserved. Other means formising and lowering the telescoping cylinder and guiding the same in itsmovements might. be substituted for those shown. The invention might beapplied to other forms of lamps and then the various details ofconstruction of the cylinder varied to suit such other forms of lamp;but all such changes I consider matters of form and not of sub stanceand as not taking the modified construction outside of the scope of myinvention.

Having therefore described my invention, what I claim as new, and desireto protect by Letters Patent, is
